[Touken Ranbu] The Sixth Demon King

One-sentence summary: (Also known as All the Swords in the Citadel Are My Ex-Boyfriends)

The moment the Master realizes that almost every historical figure looks exactly like them, the nightmare known as the Shura field begins.

Blurb:

To my Master:

I came to Kyoto Castle to become stronger.

The Kyoto Castle I remember so well. Here, I saw the past just as it used to be.

I was so happy that I ran around everywhere.

Then I met someone.

Can you guess who? The right answer is Lord Yoshitsune!

I never thought I'd get to see him again!

To my Master:

I'm now traveling with Lord Yoshitsune as he flees.

Of course, I know what happens later.

And I know that I have to protect history as it was meant to be.

But at least, I'd like to stay with him until the very end. That's allowed, isn't it?

...But I discovered something.

Last night, Lord Yoshitsune hid me away.

Today, Lord Yoshitsune said that I wasn't among the swords he possessed.

Why would he do that?

To my Master:

Lord Yoshitsune has passed away.

Things went more or less as I knew they would.

Only one thing was different.

I met Lord Yoshitsune again.

I don't understand why Lord Yoshitsune calls himself the emperor.

Still,

I have so much to learn from Lord Yoshitsune if I want to become stronger.

We'll train together and grow stronger together. And another thing... the rice at the harvest festival is the best!

Training isn't just about becoming stronger.

I still can't be of any help to you, Master.

That's what I learned on this journey.

Please don't worry about me while I'm learning from Lord Yoshitsune.

Saniwa: Time Government, why hasn't my Imanotsurugi come back from training after four days?!!!

Master: Time Government, why hasn't this Imanotsurugi left after four days?!!!!!!!

I will always protect

The history that belongs to us

For all time

Just as

You have been away from me for so long
